大气条件变化时的激光雷达散射截面测量方法

利用双光路探测研究了大气条件变化对外场目标激光雷达散射截面测量准确度的影响.将双光路探测应用于比对测量后,推导出了新的比对测量公式,进行了实验验证,并讨论了其适用条件.通过对漫反射板激光雷达散射截面的外场实测,结果表明:利用新的比对测量公式,不仅能有效减小测量过程中因大气条件变化带来的误差,提高测量准确度,而且计算过程较为简单;工程上易于实现.

Method of Laser Radar Cross Section Measuring with Atmosphere Condition Changing

Using two-channel detection,influences on laser radar cross section measure accuracy caused by atmosphere condition changing were studied.The new formula of comparing measure was deduced.An experiment was carried out on the new formula,and its using qualification was discussed.Through measuring the diffuse reflection board's LRCS in the outfield,the result indicates that the new formula can correct the measure error because of the atmosphere condition changing and help to improve measure accuracy,and its ca...
